NIM game - problem with re-runing the game

Posted 15 November 2012 - 02:00 PM

Hello,
i have to do a small game called NIM. The game is a human vs. computer game where each player removes a number of straws (1,2 or 3) and the player who removes the last straw looses. I got the game to work properly but the problem is that it doesn't want to re-run if the player wants to play again. Any help would be apprecieted. />

import random
print("""************ NIM GAME ***********

************ The rules ***********

You need to remove from 1 to 3 straws from the pile.
The player that removes the final straw is the loser.

player1=str(input("Enter your name. "))
player2="Computer"

strawsNumber+=1
def removingStrawsComputer():
removedNumber=random.randint(1,3)
global strawsNumber
while removedNumber>strawsNumber:
removedNumber=random.randint(1,3)
strawsNumber-=removedNumber
return strawsNumber

global strawsNumber

howMany=int(input("How many straws do you want to remove?(from 1 to 3) "))
if howMany>3 or howMany<1:
print("Enter a number between 1 and 3.")
else:
legalMove=True
while howMany>strawsNumber:
print("The entered number is greater than a number of straws remained.")
howMany=int(input("How many straws do you want to remove?"))
return howMany
def checkWinner(player):
if strawsNumber <=0:
print(player," wins.")

return gameover
